Ie vrrme DEVICE.

To all whom it may concern:

Be it known that I, LINUS WOLF, sub ect of the German Emperor, residingat Zurich,

1' Switzerland, have invented a certain new igniting devices for gaslamps, and has for its object to provide a new and improved dc vice ofthis description.

- The invention is illustrated in the accompanying drawings, whereintional view taken on line44 of Fig. 3;

Fig. 5 is a sectional view taken on line 5-5 of Fig. 3; Fig. 6 is a viewof the support for the spark producing device as stamped out and priorto being bent into shape.

Like numerals refer to like parts throughout the several figures.

In the drawings, I have illustrated a gas burner 1 particularly adaptedfor lamps used in connection with automobiles. A11 igniting device 2 isconnected with the burner. This igniting device comprises a supportwhich is preferably made from a single piece of metal. As herein shown,this support consists of a body portion 3 having projections 4 and 5which are provided with openings 6 for the pin 7 carrying therotatablepart of the device. Connected with the projection 5 is a piece 8 adaptedto be bent so as to form a receptacle or receiving devicefor the sparkproducing material. A stop piece 9 also projects from the body portionand acts as a stop for the rotating part. An engaging piece 10 projectsfrom the body portion and is adapted to be bent around so as to engagethe burner 1. This engaging piece is cut away at'll and there is a hookprojection 1.2 connected with the body portion to which is connected theend of the spring 13 which presses the spark producing material againstthe rotating part. The engaging part 10 is provided with an opening 1 1and a body portion with. an opening 15 which are opposed to each otherwhen the engaging part is bent around and Patented May 2, iaie.

which the igniting device is held in place 011 the burner. The supportis first stamped out as shown in. Fig.6 and the parts are then bent tothe positions shown in Figs. 1, 2 and 3. The openings'G-in theprojecting parts 4 and 5am then opposed to each other. A cylindricalpart 16 is then placed between the parts 4 and 5. This cylindrical partis supported upon the pin 7 and is. hollow, there being located insideof it a coil spring 17 having one end l8 engaging the support so as tobe held stationary. The other end is formed into a loop 19 whichprojects through a hole 20 in thecylindrical part and which actsas ahandle for rotatingthe cylindrical part. By grasping thehandle 19thecylindrical part is rotated and the spring 17 energized; When the handle19 is released, the spring presses the cylindrical part back until thespring. strikes the stop 9. Upon the end of the cylindrical part is aroughened part 21. This roughenedpartis preferably made of steel orother hardened material and may be in the form of a file. The rotatingpart is reduced in diameter near its end and the roughened part formedinto a circular form with the ends separated by a space, that is, theroughened part does not form a complete circle. A projecting part 22 onthe cylindrical part extends into the space between the ends of theroughened partso as to prevent the roughened. part from rotating onthecylindrical part. This projection may be formed in any desired manner asby upsetting or mutilating the rotating part so as to force the metalthereof outwardly at this point. The pin 7 passes through the rotatingpart and into the opening 6 and is held inplace in any desired manner asby upsetting or battering the ends thereof. The piece 8 is bent" aroundso that the ends are in proximity to each other as shown in Fig. 5 andis located above the piece of roughened material 21.

A piece 23 of spark producing material, such for example, as pyrophorusmaterial, is loosely placed in the receptacle or receiving device formedby the piece 8 and a follower device 24 is inserted therein so as toengage the spark producing metal and is force said metal against thesurface of the roughened piece 21. As illustrated in the drawing, a bolt26 1s passedthroujgh the openings 14 and 15 and is provided with a nut27* which may be tightened so as to clamp the igniting deviceto theburnerr It" will be noted that the spark producing .device consists ofthe spark producing'metal and the roughenedpiece 21 is arranged so thatthe spark'is' discharged directly toward" the burner. In other Words,there-*is a spark opening 28 arranged in the support 3 oppositethe-"burnen and this sp' 'rkopening is arranged with relation to theengagingdevice 10 sothat it wi11-point directlytoward the burnerregardless of theposition of th e-l'igniting devices In" other words; if

the-- igniting device is rotated entirely: around=*tlieburner,.thisspark opening w-ill' be pointed directly toward the burner atevery'rppint around the entire circle soas to discharge sparks directlytoward 'theb'urn'er in *every position it occupiesthroughbut itsentire'circlew It 5 will be noted" that 5 the present device is *smallso that it occupies very"v little space' burner as'shown' for exampleinFig-tl. Y The gias isrthen' turned on'and the-handle'19*is' moved awayfrom-the stop 91 This move ment 1 being; performed by the hand will becomparativelyisl'ow: After beingiimo ved a part of a*-=revolution,- th'ehandle is: released and the energized spring rapidly moves therotatingpart and the roughened part 21 back to"their initial -position; Therouglr ened part moves: along the lower surface of i the spark--producingi metal 23 at a comp'ara tively high speed and causespans-tabed'isch'arged therefrom througlrthe spark opening-28 directly"upon the gas emerging I from the end of the burner: The gas" isthereupon-' ignited."

This device" in addition"- to being simple in construction is reliableand will last 1 a longtime. It permits the burner to be lighted withoutmatches and it acts regardless of'wind, rain-or atmospheric conditions.

I claim':

1. An igniting: device "for gaslamps comprising a rotatable'p'art; a'support upon which it is mounted, a spring connected with said rotatablepart and with afixed part associated with said support, a portionof'sa'id spring bentoutward-ly so as to for'mia handie by means-ofwhichsaid movable part is moVed and Said spring energized, a' spark Copies 0!this patent may be-obtained"for producing device associated with saidmovable part and located in-the plane of the burner and an engagingdevice on said support for conneetin it with the burner.

2, An igniting device for gas lamps com- "p'risin'g a spark producingdevice, a movable part for actuating the spark producing device, asupport therefor made up of a single pieee= of--material, a portion ofsaid support bent so as to form an engaging device for the burnerg'aspring associated with said-movable part; a portion of I said springprojecting: laterally therefrom so as toact as a handle formanipul'atingit i and 1 a stop engaging said projecting portion of thespring-so" as'to limit its movement;
